3 Assignments and Viva on practical’s : 10 marks

Assessment:
Internal Assessment Test:
Assessment consists of two class tests of 15 marks each. The first class test is to be conducted when approx. 40% syllabus is completed and second class test when additional 35% syllabus is completed. Duration of each test shall be one hour.

End Semester Theory Examination:
1. Question paper will comprise of total 06 questions, each carrying 15 marks.
2. Total 04 questions need to be solved.
3. Question No: 01 will be compulsory and based on entire syllabus wherein sub-questions of
3 marks will be asked.
4. Remaining questions will be mixed in nature.( e.g. Suppose Q.2 has part (a) from module 3
then part (b) will be from any module other than module 3 )
5. In question paper weightage of each module will be proportional to number of respective
lecture hrs as mentioned in the syllabus.
